Heads up, singlespeeders! If youre trying to convert any recent model bike into a singlespeed, youve probably realized by now that since the dropouts are vertical, there isnt any way to properly tension the chain. Surly comes to the rescue with the Singleator. This handy device mounts to the derailleur hanger and provides proper chain tension in a simple, lightweight package.

Tensioner allows use of 1-speed drivetrain on vertical drop frame

Mounts to derailleur hanger, self aligning floating pulley

Adjustable chain line

anti-chain drop hoop

This part requires an 18mm Cone wrench to make it work. See the the Surly wrench below. Its the perfect fit. If you are self-installing, make sure to have one on hand. Make sure to read the instructions.

I used this component on a single speed road bike conversion. It was easy to install (I set it up to tension the chain upwards, using the supplied spring.) I used it with the Gusset single speed conversion kit...I was a little worried about the chain line, but it set up perfectly. I've been surprised at how little tension it takes for proper operation. It's quiet, and I haven't experienced any problems with the chain skipping on the cog. That may be a mountain bike only problem. All in all, a great product.

Went through a lot to dial in my singlespeed slopestyle set up and it would've been a lot easier if I started with a cheaper tensioner (ended up with the gusset) . First off the integral spring design is weak and does not provide as much tension as the lever type found on cheaper tensioners. Carrying around a cone wrench to tighten this thing on the trails is just ridiculous. There is also nothing to keep the tensioner from loosening on the hanger even though cheaper tensioners have this feature. The tensioner constantly failed with proper chain length/line and loosened all the time. The only nice part of the tensioner is the big rings that protect the pulley, I pulled them off and put them on my gusset tensioner for a sweet setup that has zero problems.

Bottom line is I wish I spoke to my LBS shop guys before I wasted money as they confirmed all of the same problems I had setting up the bike.

Absolutely did not work in push down configuration on my norco empire 5. Don't waste your money cheaper tensioners work way better! Not a single problem with my gusset

Very nice - Installation is a little tricky - not a problem, but you can't just slap it on. There are others out there that do the same thing, but I went with Surly since I knew this had to be a tried and true design - worth a few extra bucks.

I reversed the spring for the singulator to be pushing up on the chain and it works flawlessly. I've been using a standard tensioner most others have been using for years and it skips teeth and bouces around on decents. This one is dead quiet and never skips teeth even on the most grueling climbs (32x18 gearing). I like how the spring is internal and the unit is very nice looking. With the way I'm running this unit, it is almost unnoticable on the bike as it runs close the the bottom triangle rail. I love this thing.

You absolutely DO NOT need their overpriced bottle opener, the action of your Hex wrench sticks it to the frame and it's the *position* that makes tension...I really have no idea what that wrench is for.

awesome if serious about converting to SS buy it worth the coin, spring up or down both work well chain stays where it needs to be, and im riding full rigid so it rough going, just be sure to get a straight chain line
